Hello, My wife just started nursing school and they make you purchase a laptop from them. She received her MBP two weeks ago and dropped it off the side of the couch today. (charging) As luck would have it, i have some dumbbells on that side of the couch and it landed on them. Everything works, but the top case is dented and that caused the top casing to curve some. The curve is causing the MBP to not stay shut, the magnet is not strong enough. Anyone have any experience replacing the top case? Cost, how hard, where to purchase, etc..? It is a 15" btw. The screen is fine, just the casing seems to be the problem, pic attached. Thanks for your help!
